search for: mount_options

Hi, is there anybody understanding HAL? I use CentOS 4 (RHEL 4) I need set specific mount options for USB flash disk. I found I can do it in /usr/share/hal/fdi/95userpolicy/storage-policy.fdi <?xml version="1.0" encoding="ISO-8859-1"?><!-- -*- SGML -*- --> <deviceinfo version="0.2"> <device> <match key="volume.fstype"

Nikita, Please take a look at the attached patch. I have rewritten it a little, and only lightly tested it. Rich.

virt-sparsify shouldn't die if sparsifying a filesystem that contains read-only LVs. https://bugzilla.redhat.com/show_bug.cgi?id=1185561 I thought about trying to make the LV writable temporarily, but I suspect that if the sysadmin has made the LV read-only, then they probably did it for a reason, so we shouldn't touch it. Rich.

In btrfs if we mount with "compress" we have no way to disable compressing by remounting (mount -o remount /mnt/btrfs), only by unmounting and mounting without "compress". This patch adds "nocompress" mount option which can be used to remount the filesystem without compression: # mount -o remount,nocompress /mnt/btrfs This option is usefull in cases when we have a

DAX is explained in detail here: https://lwn.net/Articles/610174/ This patch adds support to supermin for using a DAX root filesystem. The corresponding libguestfs patches will be posted shortly once I've tested them a bit more. This requires qemu >= 2.6. Unfortunately it's not really a win for a few reasons: - Requires enabling ACPI, which slows everything down by hundreds of

Hi Seto, please could you update also the man page too ? Why it was not provided a way to clear a *single* flag ? To me it seems a bit too long to clear all the flag (btrfs mount-option clear) and then set the right one. As user interface I suggest something like chmod: btrfs mount-option set +ssd,skip_balance -nodatacow /dev/sdX or btrfs mount-option set =ssd,skip_balance,nodatacow

Require the root= parameter is passed to specify which root (apppliance) to mount. Libguestfs has done this since 2012. The other two patches are small code refactorings in the init program. Rich.

https://bugzilla.redhat.com/show_bug.cgi?id=1564983 Because Mount.mount_vfs was declared with the wrong type signature it could never be called correctly from outside the daemon. The root cause of this problem is that the generator doesn't generate the type signatures automatically (which it could do, and fairly easily). Therefore there are probably other similar bugs waiting to be found.
